Ste-Eulalie’s share of its area codes

Within area code 873, Ste-Eulalie accounts for only 3 of 667 prefixes (0.4%): the code is dominated by Sherbrooke and spread over 162 rate centres. Within area code 819, Ste-Eulalie accounts for only 2 of 770 prefixes (0.3%): the code is dominated by Ottawa-Hull and spread over 211 rate centres.

Who holds these numbers

TELUS Quebec holds the largest share at 2 prefixes, 40.0% of the total, ahead of 3 other carriers. Code by code: in 873, TELUS Quebec leads with 2 of 3 prefixes ahead of 1 others; in 819, 9164-3122 Quebec inc leads with 1 of 2 prefixes ahead of 1 others. No carrier holds prefixes in every one of Ste-Eulalie’s 2 area codes, while 4 appear in just one.

Wireless and wireline

None of Ste-Eulalie’s holders carries a mobility brand in its registered name: all 5 prefixes belong to wireline or wholesale carriers, among them TELUS Quebec, 9164-3122 Quebec inc, Bell Canada and Telebec Ltee. A call showing a Ste-Eulalie number therefore nominally comes from a landline, cable or VoIP platform rather than a locally assigned cellphone.

How the allocation was built up

Ste-Eulalie’s dated assignments run from 2006 to 2022. The busiest period was 2010–2014, when 2 prefixes went to 1 carrier. 1 prefixes (20%) carry no date in the register: these are the historic pre-1999 assignments, the wireline bedrock of the rate centre. Since 2020 another 1 prefixes have been added, so the rate centre is still growing.

Ste-Eulalie’s oldest prefixes, the ones the register leaves undated, belong to Telebec Ltee: this carrier made up the landscape before competition arrived. The first dated assignment went to 9164-3122 Quebec inc in 2006. The most recent arrivals are Bell Canada (2022), TELUS Quebec (2014) and 9164-3122 Quebec inc (2006), a sign that new carriers are still asking for numbers in Ste-Eulalie.

Ste-Eulalie has just 5 prefixes (50,000 numbers): a very small rate centre, typical of a village or rural area served by a single switching office.

TELUS Quebec leads with 40.0% of the prefixes, but 3 competitors have set up in Ste-Eulalie: a market where the incumbent keeps the edge without exclusivity.

Demand remains steady: 25.0% of the dated prefixes go back to the last ten years, the most active period being 2010–2014. The rate centre is growing at a regular rather than explosive pace.

Dialling a Ste-Eulalie number

Ste-Eulalie is served by 2 overlaid area codes (873 and 819). A 819 number is no more “out of town” than a 873 one; from abroad, dial +1 and the full ten digits.

The numbering neighbourhood

Ste-Eulalie shares area codes 873 and 819 with at least 20 other rate centres, including Ottawa-Hull, Sherbrooke, Trois-Rivieres, Drummondville, Gatineau, Victoriaville, Val-D'Or and Maniwaki. The largest of them, Ottawa-Hull, holds 119 prefixes in 819 and 873; the smallest on the list, Ville-Marie, has just 12.

What a Ste-Eulalie number tells you

A number attached to Ste-Eulalie tells you that its prefix was issued to a carrier for this rate centre in Quebec, most often TELUS Quebec. It does not tell you where the handset is today: a subscriber may have ported the number to any of the 4 carriers present here or to a VoIP service usable anywhere. Nor does it tell you who is calling: caller ID can be spoofed, and a Quebec area code is easy to borrow to look local.

Reading a register entry for Ste-Eulalie: code 873-201 is recorded for TELUS Quebec, so every 873-201-XXXX number (10,000 possible) descends from that assignment. “Ste-Eulalie, Quebec” there names a rate centre, not a municipality, and several area codes overlay it.
